Six-time Pro Bowl left tackle Joe Thomas, center Alex Mack, and right tackle Mitchell Schwartz are entrenched at their positions, but losing Lauvao — even for a short time — puts Pinkston squarely on the hot seat.
"Jason has been through a lot, but he's getting back to form," Chudzinski said. "I am seeing signs, especially these last few days, of improvement. I think it remains to be seen which side of the line I like him the best, but his ability to move back and forth is a good thing.
"It's a good thing for Jason and for our football team."
Running back Trent Richardson, who is recovering from a bruised right shin, could join Lauvao on the sideline against the Rams. He practiced for the second straight day, but his reps with the first-team offense were taken by former Eagles kickoff returner Dion Lewis.
"Whatever decision we come to with Trent, we will communicate that to him," Chudzinski said. "I'll also let everyone know what we've decided."
